Facebook Inc. employees knew the Cambridge Analytica political-consulting firm had mined users’ personal data but didn’t tell those users before the news became public, an attorney for the District of Columbia said in court.

D.C. Assistant Deputy Attorney General Jimmy Rock made the claim while arguing against the social network’s bid to dismiss the district’s consumer protection lawsuit against it. The British consultancy used the data to target and influence voters on behalf of Donald Trump’s 2016 presidential election campaign.
